➢ Processing in an environment with a humidity of 30-40% rh results in films
film colour will appear orange/brown after the 30 second spin coating
stage. Although the film will revert back to a bright yellow upon placing on a 90°C hotplate and appear a dark brown/grey after the thermal heating 2 stage, the films will provide poor device performance.
• Au is one of the best catalysts to make CO from electrochemical CO2 reduction with high Faradic efficiency at low overpotential.
• Oxygen evolution anode uses iridium oxide (IrO2): high activity, stability against dissolution.

having a bright yellow colour post spin coating. Placing these films on a 90°C hotplate initially maintains this film colour and after 90-120 minutes, a perovskite film will be formed with a dark brown/grey colour ➢ If, instead, the humidity of the environment is too high (>40% rh) then the
